Hint (if Google hasn't helped You yet): 1. Pick any 2-digit number and subtract the digits. Write it down! 2. Repeat until You see a pattern. 3. Try the game again
It's a very simple trick, just think what happens if you subtract the last digit from a 2 digit number.
Spoiler (select to read): >>>After subtracting the last digit, your 2 digit number always ends with a 0. That means there are just 9 combinations left, and the same gift appears 9 times in the chart, on these 9 answers.<<<
